This book was released on 2004 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper addresses previous interpretations of the origin of planar laminae and breccia networks found in carbonate rocks of the Society Cliffs Formation, which hosts numerous base metal showings and the Nanisivik zinc-lead deposit on northern Baffin Island. Field observations concerning the sedimentology of the Society Cliffs basinal laminite and the types of breccia found in laminite are presented and a new interpretation of the origin of these rocks is offered. Implications of the findings for oceanic chemistry & base metal mineralization are briefly discussed.

Book excerpt: The Milne Inlet Graben on northern Baffin Island contains unmetamorphosed sedimentary & volcanic rocks. The middle part of the Graben includes the Society Cliffs Formation, which hosts numerous base metal showings and the Nanisivik lead-zinc deposit. Known mineralization in the Graben is predominantly limited to distinct lithofacies & stratigraphic levels of that formation. Understanding the formation's composition, origin, and lateral facies relations may be critical to determining constraints on mineralization. Existing stratigraphic nomenclature for the Formation, based on a type section in the north-west part of the Graben, does not adequately characterize the lateral variations in facies from the north-west to south-east and does not account for the Formation's evolution over time. This paper critically reviews previous research on the Formation, which has focussed on the south-east part of the Graben, and fills in the gaps in knowledge about the Formation's sedimentology & stratigraphy. It describes the distribution & lateral relations of the various lithofacies and interprets the characteristics of the basins in which they were originally deposited.

Book excerpt: Dolostone mounds over 200 metres thick and over four kilometres across developed in deep water during uppermost Arctic Bay Formation shale deposition in the north-west Milne Inlet Graben on northern Baffin Island. This paper describes the geometry of hitherto unrecognized mounds that have been identified from field work in five areas: the Saint Georges Society Cliffs near Arctic Bay; beneath the Nanisivik lead-zinc deposit; Red Rock valley; Magda Lake; and Bellevue Mountain. Their lithology, lateral facies relations, and internal composition are described and an interpretation of the origin & growth of the mounds is offered. Finally, implications of mound growth & distribution for the fault-related flow of mineralizing fluids and consequent base-metal deposition are discussed.

This book was released on 2005 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper presents results from a Quaternary mapping project conducted in two areas of central mainland Nunavut that were located beneath the Keewatin Ice Divide during the last glaciation. Field work included surficial mapping, regional-scale till sampling, stratigraphic studies, and ice-flow indicator surveys. The paper summarizes the findings related to ice flow directions, patterns, and the sequence of flow events in the two map areas. Preliminary interpretations are offered of the ice flow record from the oldest recognized ice-flow events to the most recent flows.

This book was released on 2004 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper presents results from uranium-lead dating of plutonic, volcanic, & sedimentary rocks from the Southern Indian Lake to Granville Lake area of northern Manitoba. The samples analyzed were collected from a range of tectonostratigraphic settings and provide constraints on the age of volcanism & sedimentation in the Rusty Lake Belt, on the deposition of fluvial to littoral facies sediments in the Partridge Breast Belt, and on the emplacement of orthogneiss and plutonic rocks.

This book was released on 2004 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper summarizes field characteristics of volcanic & sedimentary facies along a transect within the Hazelton Group rocks in the east Telegraph Creek area of north-west British Columbia. It begins with a brief description of the geological setting, then presents facies descriptions & information on the distribution & associations of the rocks described. The facies are organized into the following mappable units: dacite-andesite breccia; coarse sandstone to conglomerate; felsic volcaniclastic & subordinate breccia & mudstone; interbedded mudstone & sandstone; and basalt.

Book excerpt: The purpose of this paper is to document results of pore size analyses of rocks from the Astarte River Formation, central Baffin Island, for use in interpreting ground electromagnetic surveys that have been conducted in the central Baffin region. Results are presented for pore size distribution analyses of four black graphitic shale samples subjected to mercury injection porosimetry measurements. These measurements are essential for the electrical mechanism analysis of these samples. Porosity values are compared to those typical of mudstone or crystalline rocks.

This book was released on 2004 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper reports the results of a mapping program in the vicinity of the Boston gold deposit near Hope Bay, south-west Nunavut. It first reviews the regional geology, the granitoid rocks of the Hope Bay volcanic belt, and their contact relationships with the belt. It then focusses on the geology of the deposit area, with descriptions of the rock types, the geologic structures, and the gold mineralization. Finally, implications of the findings for mineralization in other areas of the Hope Bay belt are discussed.
